Prayer Circles

I am asking for prayer for my father who is 83 years old. He has parkinson, Alzheimers, and dementia. He can no longer walk.He has lost over 80 lbs in the past 9 months. He now weighs 86 lbs. I am his primary care taker and the youngest of 9 siblings.I had to put him in a home so that his medical needs could be taken care of. He has been with me and my family for the last 4 years.He is dying a horrible slow death, I ask the lord why he has not taken him home.Please pray for him. I want him to be in peace and no longer suffering. Thank you.
